[1] Alternative to DickeyJohn "iSpeed Interface" (uses the same SSF setting).
[2] If the speed reading is found to be half what it should be, the likely reason is because certain (earlier specification)
instruments require a SSF expressed as metres per 2 pulses.
Satspeed 2 Operation
Limitation
This unit should not be fitted in situations where speed measurement <0.5km/hr is required, or there is consistent
poor quality GPS reception.
On initial power-up, it may take up to 5 minutes depending on the reception, to output a ground speed signal.
When used on a regular basis (daily or weekly), the startup time may be 1-2 minutes.
Bear in mind also, that the ground speed signal may be temporarily lost depending on the terrain and ground
cover (e.g. under or behind trees), and that this will be more prevalent in areas with weaker reception from a
limited no. of satellites.
Operation
The unit will automatically find the baud rate and depending on GPS reception status, provide a forward speed
signal on power up.
NOTE:
The forward speed reading will default to zero below 0.5km/hr.
